Iridium Communications Announces Merger with Rocket Lab; Credit Agreement Amended

What Happened

• Iridium Communications Inc. announced a proposed merger with Rocket Lab Corporation (Merger Agreement dated June 28, 2026). On September 15, 2026, Iridium and its subsidiaries agreed to a Consent and Amendment No. 4 (the “Fourth Amendment”) to its Amended and Restated Credit Agreement to address the transaction and lender consent.
• The company also disclosed that Rocket Lab filed a Registration Statement on Form S-4 (declared effective August 26, 2026) and Iridium distributed the definitive proxy statement/final prospectus beginning on or about August 26, 2026 seeking stockholder approval for the transaction.

Key Details

• The Fourth Amendment: (i) confirms the Transaction will not constitute a “Change of Control” under the Credit Agreement (subject to the agreement’s terms); (ii) records that the requisite lenders expressly consent to the Transaction; and (iii) provides for a downstream guarantee at closing by Rocket Lab USA, Inc., Rocket Lab’s primary operating subsidiary.
• Interest and fees (effective only after closing and subject to occurrence): interest on term loans will increase to either SOFR + 2.50%–3.00% or base rate + 1.50%–2.00% depending on Iridium’s credit ratings; a 1.00% prepayment premium for repricing transactions; and a 1.00% exit fee applicable to term loans prepaid after the first anniversary of the closing.
• The amendment permits the existing term loans under the Credit Agreement to remain outstanding after closing, subject to the other terms and conditions of the Credit Agreement.
• Administrative agent under the Credit Agreement is Deutsche Bank AG New York Branch.

Why It Matters

• For investors, lender consent and the credit amendment reduce the financing/legal risk that the merger would trigger a default or force early repayment under Iridium’s existing credit facility—helping the deal proceed without immediate debt restructuring.
• However, if the merger closes, Iridium’s borrowing costs are likely to rise due to higher interest margins and potential fees (prepayment premium and exit fee), which could increase interest expense and affect cash flow.
• The downstream guarantee by Rocket Lab USA provides additional credit support for Iridium’s obligations under the facility after closing, but also means Rocket Lab’s operating subsidiary will be contractually responsible for those obligations.
